I tried to export a folder of images from LR to a folder on my desktop. Tried exporting at full res JPEG and compressed jpeg. Also tried changing the destination folder. Lightroom starts exporting, sometimes it gets a few files exported, then it crashes.

Since this wasn't working I thought maybe I could get it to export out of Bridge. I tried changing the catalog settings in LR to write changes to XMP so I could maintain my adjustments and ratings in bridge. LR crashes immediately after checking the Write Changes to XMP check box. I had to restart LR and quickly go uncheck Write to XMP or it would crash again after restarting.
